CuEq over 158 m, Within 0.34% CuEq over 533

Grade Copper-Gold-Silver and Mineralized
Breccia Zones
Vancouver, British Columbia--(Newsfile Corp. - July 27, 2023) - Kodiak Copper Corp. (TSXV: KDK)
(OTCQB: KDKCF) (FSE: 5DD1) (the "Company" or "Kodiak") today reports drill results from the fully
funded, large drill program at its 100% owned MPD copper-gold porphyry project in southern British
Columbia. Assay results from the
first three holes drilled in 2023 at the West Zone (MPD South /
Axe claims)
are presented in this release.
Highlights
Kodiak's drilling at the West Zone to date has confirmed porphyry mineralization
from surface
over an area of 300 metres by 300 metres and up to 819 metres depth
, extending well below
historic drilling and open to extension.
A new zone of structurally hosted high-grade copper-gold-silver mineralization
has been
discovered to the east of the West Zone.
For the first time
at the MPD project, significant
mineralized hydrothermal breccia has been
drilled.
The breccia includes
copper mineralized clasts suggesting additional undrilled
mineralization at depth
.
West Zone Drill Results - Figures 1, 2, and 3, Table 1
Three drill holes were completed into the West Zone, collared near the centre of the geophysical
target and drilled to the south, vertically, and to the east.
Additional drill holes are also being
completed, with assays pending.
Drill hole AXE-23-001, drilled towards the south, intersected significant mineralization from
bedrock surface to 539 metres depth
. Assays include 0.28% Cu, 0.28 g/t Au and 0.83 g/t Ag
(0.51% CuEq*) over 158 metres
, within a broader interval of 0.18% Cu, 0.20 g/t Au and 0.61 g/t
Ag
(0.34% CuEq*) over 533 metres
.
Figure 6
.
Drill hole AXE-23-002, drilled vertically, intersected mineralization
from surface
to 488 metres
depth
, assaying 0.21% Cu, 0.30 g/t Au and 1.36 g/t Ag
(0.45% CuEq*) over 203 metres
, within
0.15% Cu, 0.16 g/t Au and 0.80 g/t Ag
(0.28% CuEq*) over 482 metres
.
Drill hole AXE-23-003, drilled to the east, also intersected
from-surface mineralization
assaying
0.22% Cu, 0.27 g/t Au and 1.08 g/t Ag
(0.44% CuEq*) over 51 metres
, within a broad interval of
0.13% Cu, 0.20 g/t Au and 0.61 g/t Ag
(0.29% CuEq*) over 209 metres
.
West Zone drilling by Kodiak and others show an approximately
1:1 ratio of g/t gold to %
copper
, similar to the central Gate Zone and usually indicative of higher temperature
mineralization.
Gold-Rich Mineralization Within the West Zone
A review of drill core from AXE-23-001, 002 and 003 suggests some of the high copper-gold-silver
values observed within the intervals reported in Table 1 also originate from interpreted north-south
trending vein-like structures that enrich the porphyry mineralization.
Examples of these are:
AXE-23-001:
5.14 g/t Au, 2.68 g/t Ag and 0.83% Cu
over 2.1 metres at 21 metres downhole
AXE-23-002:
10.7 g/t Au, 2.16 g/t Ag and 0.10% Cu
over 0.8 metres at 591 metres downhole
AXE-23-003:
9.51 g/t Au, 3.31 g/t Ag and 0.33% Cu
, over 0.9 metres at 71 metres downhole
AXE-23-003:
8.29 g/t Au, 17.15 g/t Ag and 0.13% Cu
over 0.8 metres at 192 metres downhole
New Structurally Hosted High-Grade Zone
Drilling east beyond the limits of the West Zone magnetic anomaly, drill hole AXE-23-003
intersected a new, structurally controlled high-grade copper-gold silver zone assaying
0.93% Cu,
0.64 g/t Au and 3.2 g/t Ag
(1.44% CuEq*) over 16 metres
starting at 274 metres down hole.
Figures 1, 2, 3 and 4, Table 1
.
The interval contains distinctive copper-gold-silver zone with semi-massive pyrite-chalcopyrite
mineralization in phyllic/propylitic altered andesite.
Figure 4
.
Discovery of Mineralized Hydrothermal Breccia
A new discovery was also made at depth in vertical drill hole AXE-23-002 where
mineralized
high-temperature, high-energy hydrothermal breccia was intersected
over 175 metres from
644 to 819 metres. The hole was lost prematurely in mineralization.
This is the
first significant
breccia-hosted porphyry mineralization drilled at MPD
.
Figure 5
.
The breccia contains
chalcopyrite-mineralized clasts which account for a portion of the
total mineralized grade
. In most high-energy hydrothermal breccia systems, mineralized clasts
indicate a
separate, deeper mineralized zone below the breccia
. Future drilling will test for
mineralization at depth, including the source of the mineralized clasts.
The discovery interval assayed
0.29% Cu, 0.22 g/t Au and 0.72 g/t Ag
(0.46% CuEq*) over 30
metres
, within a broader zone assaying
0.11% Cu, 0.13 g/t Au and 0.53 g/t Ag
(0.21% CuEq*)
over 175 metres
, which remains open at depth.
Figures 1, 2 and 3, Table 1
.
Claudia Tornquist, President and CEO of Kodiak said, "I am very pleased with these initial results from
our 2023 drill program. The first three holes at the West Zone are a promising start and confirm our
thesis that porphyry mineralization exists below and adjacent to shallow historic drilling. The West Zone
is only one of several targets we will test this year and I am looking forward to the next batch of results
from the Man Zone where our second drill is currently turning. In total we are aiming to test four or five
targets in 2023, each with excellent discovery potential."
Chris Taylor, Chairman of Kodiak said, "We have been looking for mineralized breccias like the ones we
have discovered beneath the West Zone since we began drilling at MPD, as higher-grade breccias are
key contributors to many alkalic porphyry mines.
We interpret both MPD North and MPD South as
overlying major structural intersections that controlled porphyry magma emplacement and are using
geophysical and drill data to define new targets within these mineralized corridors.
This approach has
proven effective in similar alkalic porphyry systems such as the Cadia-Ridgeway deposits in Australia,
and locally at many British Columbia porphyry mines including Copper Mountain, Mount Polley and Red
Chris."

Calculations are uncut and recovery is assumed to be 100% as no
metallurgical data is available.
Metal prices of US$3.75/lb copper, US$1,950/oz gold, and US$24/oz silver, using the formula: %CuEq = Cu grade +

**Intervals are downhole drilled core intervals.
Drilling data to date is insufficient to determine true width of mineralisation.
